If it shows up in disk utilities than it is mounted, just because it isn't showing on the desktop it should show up in finder.

You are passing around completely inaccurate information. "Visible to the operating system" does not equal mounted. There's a "disk" (which this is) and there's a "Volume," which is what mounts and appears on the Desktop.

If the "disk" has not been formatted with a "Volume" then the disk is indeed visible to the OS but there is nothing "mounted."

Wanting to help is great, but it's kind of like guessing at driving directions when asked, but not telling the person who's lost that you're guessing. Not such a great thing to do.

What a perfect thread - I'm having a similar problem as dashard. However, my card and reader are not "visible" to the operation system (i.e., they do not show up in disk utility). I use the card in a Canon SD750 digital camera. I've formatted the card using the camera itself, but that didn't seem to help any. My suspicion is that the card needs to be initialized, but I don't know how to do this if my computer doesn't know the card exists! Any insights are greatly appreciated!

Actually, I was saying that if you have "Show External Disks on Desktop" box unchecked as I have pictured here a volume won't be visible on the desktop BUT it would show up in Finder as I was alluding to, therefore the information I gave out was not incorrect your interpretation of it was.

Another possible solution suggestion would be if the cards (not the OP) are SDHC cards a standard card reader won't work, you'll need an SDHC reader or direct hook up to the device (i.e. camera).

Similar problem here. I just purchased an SD HC card (for whatever HD stands for) and cannot mount it when inserted in the card reader. The only way is throught USB-cable between camera and Macbook Pro. I'd like to mount and initialize it or download software that will enable the card-reader on my printer.

Any clues? Formating with the camera did not do it.

I've read somewhere on a French posting that NTFS-3G could be useful. I don't understand what it stands for and if it would work. Has anybody tried that?

Is you reader able to read SDHC cards? HC (High Capacity) cards can't be read by older readers, the newer readers are backwards compatible with standard SD cards.
